Got 50m of concrete post and panel fencing to replace, wondering if it's worth trying to get a mini crusher in to crush the gravel boards and Posts.
Got a raised patio to prep for a builder!! He must be short on work as he'd normally leave it to us but he's having a go at laying slate for the first time!
So will mini crusher chew up 7 foot posts and 1.8m gravel boards with rebar or shall I just bury them whole under the Crete.
Thinking burying them will be quicker and easier than messing with mini crusher, do you have to hand load then

Probably just bury them whole giles, the re-bar makes a mess of the conveyor so you can either hold the post until one end is crushed then turn it over, or snap in half, turn conveyor off then crush, then pull re-bar out....yes by hand lol

Still though...as much as i like the concept, youll need to park the crusher minus its conveyor where the crush is needed, ie the patio and crush it all there...the post and boards will have to be carried to it.....
Thinking about it, youd need to carry them there anyway if you are going to bury them, so it swings and roundabouts really i suppose.

Theoretically burying waste is, to the letter of law, not entirely legal (just in case the Enviro officers are trolling the forum.). Certainly in the middle of a field it'd likely (I think) be considered fly tipping and we all know the penalties.
Using it as sub-base is not a bad idea though. The halfway-house solution, especially with reinforced gear might be an excavator jaw crusher attachment like our BAV Alligator Crusher, which is more primary then processing tool, but can still produce lumps of 0-100mm and also cut and crush reinforcing wire clean for scrap.
Sandhurst Equipment rental hire these things (and other similar kit) out.

Well burying it is bad terminology,
The correct terminology might be better recycling the onsite concrete to reduce our carbon footprint and waste movements.
I don't see a difference to using them whole under the Crete to faffing around and crushing them

It's not very good building practice Giles. To bury them you will have to dig out then you have the overburden to muck away. Why not just muck away the crete ???

Dig a hole and bury them off-site somewhere when no-one is looking.
I too wouldn't keep them back for crushing, the rebar is a pain in the arse to deal with, plus the reclaimed material isn't that plentiful from posts IYKWIM.

The difference is subtle but it's there all the same.
I suppose the parallel is that to move them off site you need a waste carrier's licence, whereas if they're crushed (i.e. 'recycled' aggregate) you don't.
As long as the big lumps won't harm the quality of what's laid over them, I'd tend to agree it doesn't really matter a great deal.
FWIW it's pretty easy to crush the wires clean.

Just checked and the one we had on the shelf was sold and has not (yet) been replaced. We can normally get one of these done within 3 or 4 days though. And of course we'll look after you as far as possible on price.
Drop an enquiry to our normal sales email and they'll sort it. (I'm away from the office for a while, oterwise you could PM.)
